M20-8761446 Equivalent & Substitute Parts

Part Overview

The M20-8761446 is a surface mount rectangular connector header manufactured by Harwin Inc., featuring 28 positions with 0.100" (2.54mm) pitch in a 2-row configuration. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 28 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.100" (2.54mm) — exact match required
• Mounting Type: Surface Mount — exact match required
• Termination: Solder — exact match required
• Contact Type: Male Pin — exact match required
• Current Rating: 3A per Contact — minimum requirement
• Voltage Rating: 250V — minimum requirement
• Material Flammability Rating: UL94 V-0 — minimum requirement
• RoHS Status: ROHS3 Compliant — minimum requirement

The following parts meet all substitution criteria:

1. 95278-101-28LF (Amphenol ICC / FCI) — Direct 28-position equivalent
2. 95278-801-28LF (Amphenol ICC / FCI) — Direct 28-position equivalent
3. GBC14DABN-M30 (Sullins Connector Solutions) — Direct 28-position equivalent
4. M20-8761842 (Harwin Inc.) — Same manufacturer, 36-position variant (position count differs; use only when application permits increased connector capacity)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (28-Position, Direct Equivalents):

• 95278-101-28LF — Recommended for applications requiring maximum inventory availability. Amphenol ICC BERGSTIK® series offers extended operating temperature range (-65°C ~ 125°C) and gold-plated mating contacts with GXT™ finish (30.0µin thickness). Active product status with 6526 units in stock.

• 95278-801-28LF — Suitable for cost-optimized designs. Amphenol ICC BERGSTIK® series with gold-plated mating contacts (15.0µin GXT™ finish). Active product status with 1007 units in stock.

• GBC14DABN-M30 — Recommended for high-temperature applications. Sullins Connector Solutions offering extended operating temperature range (-65°C ~ 150°C) and polyamide (PA9T) insulation material. Active product status with 1100 units in stock.

Secondary Substitute (36-Position Variant):

• M20-8761842 — Harwin Inc. same-manufacturer alternative with identical electrical and mechanical specifications except position count (36 vs. 28). Use only when application design permits increased connector capacity or when 28-position variants are unavailable. Active product status with 1136 units in stock.

All substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Selection should prioritize inventory availability, operating temperature requirements, and contact finish specifications for the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can 95278-101-28LF and 95278-801-28LF be used interchangeably?

A: Both parts are Amphenol ICC BERGSTIK® 28-position headers with identical pitch, row spacing, mounting type, and termination. The primary difference is contact finish thickness on the mating surface (30.0µin vs. 15.0µin gold plating). Selection depends on application contact wear requirements and cost considerations.

Q: Is M20-8761842 a direct replacement for M20-8761446?

A: M20-8761842 shares the same manufacturer, pitch, row spacing, mounting type, and electrical ratings. However, it features 36 positions instead of 28. Use only when the application design accommodates the additional connector positions or when 28-position alternatives are unavailable.

Q: What are the key differences between Amphenol ICC and Sullins alternatives?

A: Amphenol ICC (95278 series) offers extended operating temperature (-65°C ~ 125°C) with phosphor bronze contacts and gold GXT™ finish. Sullins (GBC14DABN-M30) provides the highest operating temperature range (-65°C ~ 150°C) with polyamide (PA9T) insulation and phosphor bronze contacts with gold finish. Both meet all electrical and compliance requirements.

Q: Does contact material (brass vs. phosphor bronze) affect substitution eligibility?

A: Contact material differences do not disqualify substitution when all critical parameters (pitch, position count, row spacing, mounting type, termination, current rating, voltage rating, and flammability rating) are met. Material selection affects mechanical durability and contact resistance characteristics but does not prevent functional equivalence in standard applications.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts meet RoHS compliance requirements. M20-8761446, M20-8761842, and GBC14DABN-M30 are ROHS3 Compliant. Amphenol ICC parts (95278-101-28LF and 95278-801-28LF) are RoHS Compliant. Both compliance levels are acceptable for equivalent substitution.

Q: What is the significance of the breakaway vs. cuttable connector type designation?

A: M20-8761446 is designated as cuttable, while Amphenol ICC and Sullins alternatives are designated as breakaway. Both types support the same 0.100" (2.54mm) pitch and allow individual position separation. The designation reflects manufacturing design; functional compatibility remains unchanged for standard board-to-board applications.
