Equivalent & Substitute Parts for Molex 0874271603

Part Overview

The Molex 0874271603 is a rectangular connector header, right-angle configuration, with 16 positions at 4.2mm pitch. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. The part functions as a through-hole solder-terminated header for board-to-cable/wire applications in general purpose, industrial, and telecommunications environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0874271603 is determined by strict equivalence across the following critical parameters:

• 16-position connector with 2-row configuration
• 0.165" (4.20mm) mating pitch and row spacing
• Right-angle through-hole mounting with solder termination
• Shrouded 4-wall design with locking ramp fastening
• Male pin contact type
• Tin contact finish on mating surface
• UL94 V-0 flammability rating
• ROHS3 compliance and MSL 1 rating

Two substitute parts meet these criteria: the Molex 0874271602 (direct manufacturer equivalent, active status) and the Samtec IPBT-108-H1-T-D-RA-K (cross-manufacturer alternative, active status).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874271602 serves as the primary substitute for the obsolete Molex 0874271603. Both parts are manufactured by Molex, share identical electrical and mechanical specifications, and maintain equivalent compliance certifications (ROHS3, UL94 V-0, MSL 1). The 0874271602 is active in production with significantly higher inventory availability (12423 units versus 739 units for the obsolete part).

The Samtec IPBT-108-H1-T-D-RA-K represents a cross-manufacturer alternative that maintains dimensional and functional compatibility across all critical mating parameters. Differences include insulation material composition (Liquid Crystal Polymer versus Polyamide), contact material (Copper Alloy versus Brass), and minor dimensional variations in post length and insulation height. The Samtec part provides specified operating temperature range (-55°C to 105°C) and voltage ratings (400VAC, 565VDC) not documented for the Molex variants. These differences do not preclude functional substitution in applications where the original Molex part was specified, provided the design accommodates the dimensional tolerances and material properties of the alternative.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874271602 be used as a direct replacement for the Molex 0874271603?

A: Yes. The 0874271602 is functionally and mechanically equivalent to the obsolete 0874271603. Both parts share identical pitch, position count, mounting configuration, and compliance ratings. The primary difference is product status: the 0874271602 is active in production.

Q: What are the key differences between the Molex 0874271602 and Samtec IPBT-108-H1-T-D-RA-K?

A: Both parts maintain equivalent mating pitch (4.20mm), position count (16), and mounting configuration (right-angle through-hole). Differences include insulation material (Polyamide versus Liquid Crystal Polymer), contact material (Brass versus Copper Alloy), post length (0.130" versus 0.147"), and insulation height (0.394" versus 0.424"). The Samtec part includes specified operating temperature and voltage ratings.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The Molex 0874271602 is supplied in tray packaging, while the Samtec IPBT-108-H1-T-D-RA-K is supplied in tube packaging. Procurement and assembly processes may require adjustment based on packaging format and handling requirements.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, UL94 V-0 rated, and classified as MSL 1 (Unlimited moisture sensitivity level). REACH status is unaffected for all variants.

Q: Which substitute part should be selected for new designs?

A: The Molex 0874271602 is recommended for designs requiring direct manufacturer continuity and identical specifications. The Samtec IPBT-108-H1-T-D-RA-K is suitable for applications requiring specified operating temperature range and voltage ratings, provided the dimensional variations are accommodated in the design.
