TE Connectivity 2-87215-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-87215-7 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 54 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable applications. The connector utilizes male pins with gold-plated phosphor bronze contacts and unshrouded thermoplastic insulation rated UL94 V-0.

The 2-87215-7 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design compatibility in legacy systems and to provide alternative sourcing options where original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-87215-7 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 54
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Shrouding: Unshrouded

Secondary Compatibility Factors:

• Contact material: Phosphor Bronze
• Insulation material composition
• Operating temperature range
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts identified—Amphenol ICC (FCI) 78548-554, Amphenol ICC (FCI) 78548-654, Samtec BBD-127-T-A, and Samtec BBD-127-T-B—satisfy the primary matching criteria. Variations in contact finish, contact length, insulation height, and post length represent design differences within the same functional connector class and do not preclude substitution where mechanical and electrical envelope constraints permit.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-87215-7 (Original Part)

The original part is classified as obsolete and carries ROHS3 compliance. Current inventory availability is 722 pieces. This part should be selected only when existing designs require exact form-factor compatibility or when legacy system documentation specifies this exact part number.

Amphenol ICC 78548-554 and 78548-654 (BERGSTIK® II Series)

Both Amphenol ICC parts are active products with higher inventory availability (1126 and 960 pieces respectively). These connectors feature kinked pin termination in addition to solder termination, which provides enhanced mechanical retention during assembly. Both parts carry UL94 V-0 flammability rating and MSL 1 classification.

Critical Compliance Note: Both Amphenol ICC parts are RoHS non-compliant. Selection of these parts is restricted to applications where RoHS compliance is not a regulatory requirement. The 78548-654 variant matches the original part's contact finish thickness of 30.0µin (0.76µm), while the 78548-554 variant specifies 15.0µin (0.38µm).

Samtec BBD-127-T-A and BBD-127-T-B (BBD Series)

Both Samtec parts are active products with ROHS3 compliance and REACH unaffected status. These connectors feature tin-plated mating contacts with nickel-plated posts. Operating temperature range extends to -55°C ~ 125°C, exceeding the original part's -65°C ~ 105°C range.

Mechanical Envelope Consideration: The Samtec parts exhibit significant variation in insulation height and overall contact length compared to the original part. BBD-127-T-A specifies 0.211" (5.35mm) insulation height and 0.460" (11.68mm) overall contact length. BBD-127-T-B specifies 0.335" (8.51mm) insulation height and 0.585" (14.86mm) overall contact length. These dimensional differences require board layout and mating connector clearance verification before selection.

Recommended Selection Criteria:

For RoHS3-compliant applications requiring active product status, select Samtec BBD-127-T-A or BBD-127-T-B based on mechanical envelope requirements.

For applications where RoHS compliance is not mandated and kinked pin termination is beneficial, select Amphenol ICC 78548-654 for contact finish thickness matching or 78548-554 for alternative finish specification.

For legacy systems requiring exact dimensional and electrical compatibility with minimal design modification, retain the original TE Connectivity 2-87215-7 where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 78548-554 and 78548-654 be used interchangeably with the TE Connectivity 2-87215-7?

A: Both Amphenol ICC parts satisfy the core functional requirements: 54-position, 2-row header with 0.100" (2.54mm) pitch, through-hole mounting, push-pull fastening, and unshrouded design. The primary differences are contact finish thickness (15.0µin vs. 30.0µin for the 654 variant), kinked pin termination addition, and RoHS non-compliance status. Interchangeability depends on application-specific requirements for contact finish durability and regulatory compliance.

Q: What is the significance of kinked pin termination in the Amphenol ICC parts?

A: Kinked pin termination provides mechanical retention during solder reflow by anchoring the pin within the PCB hole before solder solidification. This feature reduces the risk of pin migration during thermal cycling and improves assembly reliability. The original TE Connectivity part does not specify kinked pin termination.

Q: Why do the Samtec BBD-127-T-A and BBD-127-T-B have different insulation heights?

A: The insulation height variation reflects different connector body profiles within the same BBD series. BBD-127-T-A specifies 0.211" (5.35mm) insulation height with 0.460" (11.68mm) overall contact length, while BBD-127-T-B specifies 0.335" (8.51mm) insulation height with 0.585" (14.86mm) overall contact length. These variants accommodate different mating connector depths and board-to-board spacing requirements.

Q: Are the Samtec BBD parts compatible with the original TE Connectivity mating connectors?

A: The Samtec BBD parts maintain the same 54-position, 2-row configuration with 0.100" (2.54mm) pitch spacing. However, the contact shape differs (circular for Samtec versus circular for the original TE part). Mating connector compatibility requires verification of contact geometry and overall connector body dimensions. Consult mating connector specifications before substitution.

Q: What is the impact of contact finish differences between substitute parts?

A: The original TE Connectivity part specifies gold plating at 30.0µin (0.76µm) thickness on both mating and post contacts. Amphenol ICC 78548-654 matches this specification, while 78548-554 specifies 15.0µin (0.38µm). Samtec BBD parts specify tin plating on mating contacts with nickel plating on posts. Gold plating provides superior corrosion resistance and lower contact resistance over extended service life. Tin plating is suitable for controlled indoor environments but may exhibit higher contact resistance degradation in corrosive atmospheres.

Q: Which substitute part is recommended for new designs?

A: For new designs, Samtec BBD-127-T-A or BBD-127-T-B are recommended based on active product status, ROHS3 compliance, and extended operating temperature range (-55°C ~ 125°C). Selection between the two variants depends on mechanical envelope constraints and mating connector depth requirements. Verify insulation height and overall contact length compatibility with PCB layout and mating connector specifications.

Q: What is the RoHS compliance status of each part?

A: TE Connectivity 2-87215-7 is ROHS3 compliant. Amphenol ICC 78548-554 and 78548-654 are RoHS non-compliant. Samtec BBD-127-T-A and BBD-127-T-B are ROHS3 compliant. RoHS compliance is mandatory for products sold in the European Union and for many OEM supply chains. Verify regulatory requirements before selecting non-compliant alternatives.

Q: Are all substitute parts available in the same packaging as the original?

A: No. The original TE Connectivity part packaging is not specified. Amphenol ICC parts are supplied in bulk packaging, while Samtec BBD parts are supplied in tube packaging. Packaging differences may affect handling, storage, and assembly line integration. Confirm packaging compatibility with procurement and assembly processes.

Q: What is the current inventory status of each part?

A: TE Connectivity 2-87215-7: 722 pieces. Amphenol ICC 78548-554: 1126 pieces. Amphenol ICC 78548-654: 960 pieces. Samtec BBD-127-T-A: 1169 pieces. Samtec BBD-127-T-B: 746 pieces. Inventory levels are subject to change. Confirm availability with suppliers before design finalization.
