ESPM02100 Equivalent & Substitute Parts

Part Overview

The ESPM02100 is a 2-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire connections. This component operates at 30 A and 300 V, accommodating wire gauges from 10-30 AWG through screw-based rising cage clamp termination. The part is currently active in production with 1152 units in stock. Equivalent parts are identified when substitute components maintain identical electrical ratings, mechanical pitch, mounting configuration, and wire termination methodology, enabling direct board-level replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESPM02100 is determined by strict equivalence across the following parameters: 2-position configuration, 6.35mm pitch, horizontal board-mounted orientation, 30 A current capacity, 300 V voltage rating, through-hole mounting, and screw-based wire termination with rising cage clamp mechanism. All substitute parts must maintain polyamide housing material and side interlocking features. Wire gauge compatibility is evaluated within the specified range; parts supporting 10-30 AWG are fully equivalent, while parts supporting narrower ranges (10-24 AWG) remain functionally compatible for applications within their specified limits. Operating temperature range and compliance certifications are documented but do not restrict substitution eligibility when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and meet RoHS compliance requirements. The ESPM02100 and 796740-2 both feature rising cage clamp wire termination, providing identical mechanical engagement characteristics. The 0393800102 employs standard screw termination without the rising cage clamp specification, though it maintains equivalent electrical performance. Wire gauge compatibility differs: the ESPM02100 and 0393800102 support 10-30 AWG, while the 796740-2 supports 10-24 AWG. For applications requiring wire gauges between 25-30 AWG, the ESPM02100 or 0393800102 are required. The 796740-2 is suitable for applications within the 10-24 AWG range. All parts are RoHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings, supporting deployment in standard industrial environments without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0393800102 (Molex) directly replace the ESPM02100 in all applications?

A: The 0393800102 maintains electrical equivalence (30 A, 300 V) and mechanical compatibility (2-position, 6.35mm pitch, through-hole mounting). Both support 10-30 AWG wire gauges. The primary difference is wire termination methodology: the ESPM02100 uses rising cage clamp termination, while the 0393800102 uses standard screw termination. Both are functionally equivalent for board-level replacement.

Q: What is the wire gauge limitation of the 796740-2 (TE Connectivity)?

A: The 796740-2 supports wire gauges from 10-24 AWG, compared to the ESPM02100's 10-30 AWG range. Applications requiring 25-30 AWG wire connections must use the ESPM02100 or 0393800102. For applications within the 10-24 AWG range, the 796740-2 is fully compatible.

Q: Are all three parts suitable for 300 V applications?

A: Yes. All three parts are rated for 300 V operation and carry identical voltage specifications.

Q: What is the difference between rising cage clamp and standard screw termination?

A: Rising cage clamp termination (ESPM02100, 796740-2) provides automatic wire positioning during screw tightening, improving consistency and reducing installation variability. Standard screw termination (0393800102) requires manual wire positioning before clamping. Both methods achieve equivalent electrical and mechanical performance when properly installed.

Q: Do packaging differences affect substitution eligibility?

A: The ESPM02100 is supplied in tray packaging, the 0393800102 in tray packaging, and the 796740-2 in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects supplier logistics and inventory management practices.

Q: Are all parts RoHS compliant?

A: Yes. The ESPM02100 is RoHS Compliant, while the 0393800102 and 796740-2 are ROHS3 Compliant. All meet current RoHS requirements for lead-free manufacturing.
