TE Connectivity AMP Connectors 535512-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 535512-7 is a 50 position receptacle connector featuring 0.100" (2.54mm) pitch, through-hole right-angle mounting, and gold-plated mating contacts. This connector is part of the AMPMODU Mod II series and is designed for board-to-board applications with push-pull fastening. The product is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 535512-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 50
• Mating pitch: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Termination: Solder
• Fastening type: Push-pull
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Contact material: Phosphor bronze

Allowable Variations:

• Contact finish on mating surface (gold or tin)
• Insulation material composition (polyester or liquid crystal polymer, both glass-filled)
• Current rating (equal to or greater than 2A)
• Voltage rating (when specified)
• RoHS compliance status
• Insulation height (within mechanical tolerance)
• Contact post length (within mechanical tolerance)

The Samtec Inc. Tiger Claw™ BCS series connectors BCS-125-S-D-HE and BCS-125-T-D-HE meet all mandatory matching parameters and are therefore qualified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

BCS-125-S-D-HE (Samtec Inc.) - Gold Plated Mating Contacts

The BCS-125-S-D-HE is the primary substitute for applications requiring gold-plated mating contact finish matching the original 535512-7 specification. This connector maintains identical mating contact finish (gold at 30.0µin thickness), identical electrical and mechanical parameters, and is currently in active production status. The BCS-125-S-D-HE offers enhanced current rating (4.6A per contact versus 2A) and specified voltage rating (475VAC). The connector is ROHS3 compliant, addressing regulatory requirements that the original discontinued part does not meet. Insulation material composition differs (liquid crystal polymer versus polyester), both glass-filled and meeting UL94 V-0 flammability requirements. Minor dimensional variations exist in insulation height and contact post length within acceptable mechanical tolerances.

BCS-125-T-D-HE (Samtec Inc.) - Tin Plated Mating Contacts

The BCS-125-T-D-HE is a secondary substitute for applications where mating contact finish material is not a critical specification. This connector provides identical electrical and mechanical functionality with tin-plated mating contacts instead of gold. All other parameters match the primary substitute, including current rating (4.6A per contact), voltage rating (475VAC), operating temperature range, flammability rating, and active production status. ROHS3 compliance is maintained. Selection of this variant is appropriate for cost-sensitive applications or where contact finish material does not impact system performance.

Both Samtec substitutes provide superior current-carrying capacity and active product status, supporting long-term supply chain continuity compared to the discontinued TE Connectivity original part.

Frequently Asked Questions (FAQ)

Q: Can BCS-125-S-D-HE and BCS-125-T-D-HE be used interchangeably with 535512-7?

A: Both Samtec connectors are mechanically and electrically compatible with the 535512-7 for board-to-board applications. The primary difference is mating contact finish: BCS-125-S-D-HE provides gold plating matching the original specification, while BCS-125-T-D-HE uses tin plating. Selection depends on application requirements for contact finish material.

Q: What are the dimensional differences between the original part and substitutes?

A: Insulation height differs by 0.028" (0.72mm), with Samtec parts measuring 0.210" versus the original 0.238". Contact post length is 0.010" (0.25mm) longer on Samtec parts (0.125" versus 0.115"). These variations remain within standard mechanical tolerances for through-hole PCB mounting and do not affect functional compatibility.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both BCS-125-S-D-HE and BCS-125-T-D-HE are ROHS3 compliant. The original 535512-7 is RoHS non-compliant. This compliance improvement in substitute parts addresses current regulatory requirements for electronic components.

Q: What is the current rating difference, and does it affect compatibility?

A: The original 535512-7 is rated at 2A, while both Samtec substitutes are rated at 4.6A per contact. This represents an increase in current-carrying capacity. Substitutes are compatible with applications designed for the original 2A rating and provide additional margin for higher-current applications.

Q: Do the substitute parts have specified voltage ratings?

A: Yes. Both BCS-125-S-D-HE and BCS-125-T-D-HE are rated at 475VAC. The original 535512-7 does not specify a voltage rating in the provided data. The specified voltage rating on substitutes provides additional design documentation for system-level electrical specifications.

Q: What insulation material is used in the substitute parts?

A: Samtec substitutes use liquid crystal polymer (LCP), glass-filled insulation, compared to polyester, glass-filled insulation in the original part. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range of -55°C to 125°C.

Q: Are there packaging differences between the original and substitute parts?

A: The original 535512-7 packaging is not specified in the provided data. Both Samtec substitutes are supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the contact material composition for all three connectors?

A: All three connectors use phosphor bronze as the contact material, ensuring consistent electrical and mechanical contact properties across the original and substitute parts.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is appropriate based on contact finish requirements. BCS-125-S-D-HE is recommended when gold-plated mating contacts are specified. BCS-125-T-D-HE is suitable for applications where contact finish material is not a critical parameter. Both parts offer active production status, ROHS3 compliance, and superior current ratings compared to the discontinued original part.
