Harwin M20-9710845 Equivalent & Substitute Parts

Part Overview

The Harwin M20-9710845 is a rectangular connector header, right-angle mounted, with 8 positions at 0.100" (2.54mm) pitch. This through-hole component features male pins, solder termination, and is designed for board-to-board or cable applications. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-9710845 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 8 — exact match required
• Number of Rows: 1 — exact match required
• Mounting Type: Through Hole, Right Angle — exact match required
• Contact Type: Male Pin — exact match required
• Fastening Type: Push-Pull — exact match required
• Connector Style: Board to Board or Cable — exact match required
• Termination: Solder-compatible — acceptable variations include Kinked Pin with Solder
• Shrouding: Unshrouded — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required
• RoHS Status: ROHS3 Compliant — exact match required

All four substitute parts meet these criteria. Minor variations in contact length, insulation height, and contact finish thickness are within acceptable engineering tolerances for this connector category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Harwin M20-9960845

The M20-9960845 is the manufacturer-recommended substitute from Harwin Inc. It maintains identical electrical and mechanical specifications to the M20-9710845, including operating temperature range (-40°C ~ 105°C), current rating (3A per contact), and insulation material composition. This part is active in production with 2,882 units in stock. Selection of this part eliminates cross-manufacturer compatibility considerations and maintains design continuity within the Harwin M20 series.

Secondary Recommendations: Molex KK254 Series (0022288084, 0022289080, 0022289082)

All three Molex alternatives from the KK254 series (base product 002228) are active, ROHS3 compliant, and meet the core substitution criteria. These parts are suitable where cross-manufacturer sourcing is acceptable:

• 0022288084: Gold-plated mating contacts, standard solder termination. Recommended for applications requiring gold contact finish consistency.
• 0022289080: Tin-plated mating contacts, kinked pin termination. Suitable for applications where tin finish is acceptable and kinked pin geometry provides additional mechanical retention.
• 0022289082: Gold-plated mating contacts, kinked pin termination. Combines gold finish with kinked pin termination for enhanced mechanical stability.

All Molex alternatives carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level, matching the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q: Can the M20-9960845 be used as a direct replacement for the M20-9710845?

A: Yes. The M20-9960845 is the manufacturer-recommended substitute with identical pitch (0.100"), position count (8), mounting type (through-hole right-angle), and operating temperature range (-40°C ~ 105°C). Both parts are ROHS3 compliant and UL94 V-0 rated.

Q: What is the difference between the Harwin M20-9960845 and the Molex 0022288084?

A: Both parts share the same 0.100" pitch, 8-position configuration, and push-pull fastening. The primary differences are manufacturer (Harwin vs. Molex), connector type designation (Cuttable vs. Breakaway), and minor variations in contact length and insulation height. These differences do not affect functional compatibility in standard board-to-board or cable applications.

Q: Why do the Molex parts (0022289080 and 0022289082) have longer post lengths (0.135" vs. 0.118")?

A: The extended post length (0.135" vs. 0.118") in the Molex kinked pin variants provides additional solder joint engagement and mechanical retention. This is a design variation within the KK254 series and does not prevent substitution, provided PCB pad layout accommodates the longer post geometry.

Q: Are the Molex parts with tin-plated mating contacts (0022289080) compatible with gold-plated receptacles?

A: Tin and gold contact finishes are both acceptable for mating with standard receptacles in this connector category. However, if the mating receptacle is specifically designed for gold-plated contacts, the gold-plated Molex alternatives (0022288084 or 0022289082) are preferred to maintain consistent contact finish pairing.

Q: Do all substitute parts meet the same compliance standards as the original M20-9710845?

A: Yes. All four substitute parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level, matching the original part's compliance profile.

Q: What is the difference between kinked pin and standard solder termination?

A: Standard solder termination (M20-9960845, 0022288084) uses straight pins for through-hole mounting. Kinked pin termination (0022289080, 0022289082) incorporates a bend in the pin geometry, providing additional mechanical retention and solder joint strength. Both termination types are solder-compatible and suitable for standard PCB assembly processes.
