Molex 0874272012 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0874272012 is an active-status rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This Mini-Fit Jr 87427 series component features a 20-position, 2-row configuration with 0.165" (4.20mm) pitch and shrouded 4-wall design. The connector employs solder termination with locking ramp fastening and is widely used in general purpose, industrial, and telecommunications applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, ensuring functional compatibility in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874272012 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (20 positions, 2 rows)
• Mating pitch and row spacing (0.165" / 4.20mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Regulatory compliance (ROHS3, UL94 V-0)

The Samtec Inc. IPBT-110-H1-T-D-RA-GP meets all critical substitution criteria. Both connectors share identical position count, pitch spacing, mounting orientation, shrouding configuration, and termination approach. Both maintain active product status and comply with ROHS3 and UL94 V-0 standards. Differences in contact material (Copper Alloy vs. Brass), insulation material (LCP vs. Polyamide), and operating temperature range do not preclude functional substitution when application requirements align with the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0874272012 and Samtec IPBT-110-H1-T-D-RA-GP maintain active product status and satisfy ROHS3 compliance and UL94 V-0 flammability requirements. Selection between these parts should be based on application-specific requirements not fully specified in the original component data, such as operating temperature range, voltage rating, and mechanical tolerance stack-up considerations related to insulation height and contact length variations.

The Samtec substitute provides documented operating temperature range (-55°C ~ 105°C) and voltage rating (400VAC, 565VDC), which may be advantageous for applications requiring explicit thermal or electrical performance specifications. The Molex original part remains the preferred choice when exact form-factor compatibility with existing mating connectors or cable assemblies is required.

Frequently Asked Questions (FAQ)

Q: Can the Samtec IPBT-110-H1-T-D-RA-GP directly replace the Molex 0874272012 in existing assemblies?

A: Direct mechanical and electrical substitution is supported based on matching pitch (0.165" / 4.20mm), position count (20), row configuration (2 rows), mounting type (through-hole right-angle), and shrouding design (4-wall). However, minor dimensional differences exist in insulation height (0.394" vs. 0.424") and contact post length (0.130" vs. 0.147"), which may affect mating clearances with existing cable connectors or receptacles. Physical fit verification is necessary before production implementation.

Q: What are the key differences between these two connector headers?

A: The primary differences are contact material (Brass vs. Copper Alloy), insulation material (Polyamide vs. Liquid Crystal Polymer), and documented performance specifications. The Samtec part provides explicit operating temperature (-55°C ~ 105°C) and voltage rating (400VAC, 565VDC) data, while the Molex part does not specify these parameters. Both employ identical pitch, position count, mounting orientation, and fastening mechanisms.

Q: Are both parts suitable for industrial and telecommunications applications?

A: The Molex 0874272012 is explicitly rated for general purpose, industrial, and telecommunications applications. The Samtec IPBT-110-H1-T-D-RA-GP does not specify application categories in the provided data. Both parts meet UL94 V-0 flammability and ROHS3 compliance requirements applicable to industrial and telecommunications environments.

Q: What packaging differences exist between these parts?

A: The Molex 0874272012 is supplied in Tray packaging, while the Samtec IPBT-110-H1-T-D-RA-GP is supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility but may influence inventory handling, storage, and procurement logistics.

Q: How do the contact length specifications affect substitution?

A: Contact length differences (Mating: not specified vs. 0.260"; Post: 0.130" vs. 0.147") may impact mating depth and engagement force with corresponding receptacle connectors. Applications with tight mechanical tolerances or specific mating force requirements should evaluate these dimensional variations before substitution.
