Harwin M20-9713546 Equivalent & Substitute Parts

Part Overview

The Harwin M20-9713546 is a rectangular connector header, right-angle configuration, with 35 positions at 2.54mm pitch. This through-hole, solder-terminated component is designed for board-to-board or cable connections in general-purpose applications. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design work, maintenance, and production continuity. Active alternatives from Molex and Preci-Dip provide functional equivalence with maintained availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Harwin M20-9713546 is determined by the following critical parameters:

• 35-position configuration at 0.100" (2.54mm) pitch
• Male pin contact type
• Through-hole, right-angle mounting
• Solder termination with push-pull fastening
• Unshrouded, single-row design
• UL94 V-0 flammability rating
• ROHS3 compliance and MSL 1 rating

The three substitute parts—Molex 0022288350, Molex 0022288352, and Preci-Dip 890-80-035-20-002101—meet these core electrical and mechanical requirements. Variations in contact finish (tin versus gold), contact length specifications, and insulation height fall within acceptable tolerances for functional equivalence in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory alignment.

Molex 0022288350 and 0022288352 are functionally equivalent alternatives with minor dimensional variations in contact length and insulation height. The primary distinction between these two Molex options is the contact finish: 0022288350 features tin plating on mating contacts, while 0022288352 features gold plating. Gold-plated contacts (0022288352) provide enhanced corrosion resistance and are suitable for applications requiring extended shelf life or exposure to corrosive environments.

Preci-Dip 890-80-035-20-002101 matches the original Harwin part more closely in contact length and insulation height specifications. This part also maintains the 3A current rating and extends the operating temperature range to -55°C ~ 125°C with a 150VDC voltage rating, making it suitable for industrial and automotive applications requiring wider temperature tolerance.

Selection should be based on specific application requirements: use Molex 0022288350 for standard applications, Molex 0022288352 for environments requiring enhanced contact durability, and Preci-Dip 890-80-035-20-002101 for applications demanding extended temperature range or higher voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0022288350 and 0022288352 be used interchangeably with the Harwin M20-9713546?

A: Both Molex parts are functionally equivalent substitutes. The primary difference is contact finish: 0022288350 uses tin plating, while 0022288352 uses gold plating. Both maintain the 35-position, 2.54mm pitch configuration and through-hole right-angle mounting. Minor variations in contact length (0.244" versus 0.276") and insulation height (0.098" versus 0.100") are within acceptable tolerances for standard board-to-board applications.

Q: What are the key differences between the Molex and Preci-Dip substitutes?

A: Molex parts (0022288350 and 0022288352) feature slightly shorter mating contact length (0.244") and reduced insulation height (0.098"). Preci-Dip 890-80-035-20-002101 maintains dimensional parity with the original Harwin part (0.276" mating contact length, 0.100" insulation height) and provides extended operating temperature range (-55°C ~ 125°C) and specified voltage rating (150VDC).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts—Molex 0022288350, Molex 0022288352, and Preci-Dip 890-80-035-20-002101—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compliance and storage flexibility.

Q: Which substitute should I select for high-reliability applications?

A: For applications requiring extended temperature range and specified voltage ratings, Preci-Dip 890-80-035-20-002101 is recommended. For applications where contact corrosion resistance is critical, Molex 0022288352 with gold-plated mating contacts is appropriate. For standard general-purpose applications, Molex 0022288350 provides cost-effective equivalence.

Q: Are there packaging considerations when switching to substitute parts?

A: All substitute parts are supplied in bulk packaging. Verify tape-and-reel or tube availability with your supplier if specific packaging formats are required for automated assembly processes.
