Substitute Part Grouping Explanation
Substitution eligibility for the M20-9713845 is determined by the following critical parameters:
- Connector Type & Configuration: Header, through-hole, right-angle mounting
- Electrical Interface: 38 positions at 0.100" (2.54mm) pitch, male pin contact
- Electrical Performance: 3A per contact minimum current rating
- Physical Mounting: Through-hole solder termination with push-pull fastening
- Contact Geometry: Square contact shape with gold mating surface finish
- Insulation Material: Polyamide (PA/Nylon) construction
- Compliance: ROHS3 compliant, UL94 V-0 flammability rating
The substitute part 890-70-038-20-002101 (Preci-Dip) satisfies all critical substitution criteria. Both parts share identical pitch, position count, mounting method, contact configuration, and termination type. The substitute maintains equivalent electrical performance with enhanced operating temperature range (-55°C ~ 125°C vs. -40°C ~ 105°C) and active product status.

Engineering Selection Recommendations
The 890-70-038-20-002101 (Preci-Dip) is a direct functional equivalent to the M20-9713845. Both connectors meet ROHS3 compliance and UL94 V-0 flammability requirements. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The extended operating temperature range of the Preci-Dip connector (-55°C ~ 125°C) provides additional thermal margin compared to the Harwin original (-40°C ~ 105°C), making it suitable for applications requiring broader environmental tolerance. All critical electrical and mechanical parameters remain equivalent, supporting direct substitution in existing designs.
Frequently Asked Questions (FAQ)
Q: Can the 890-70-038-20-002101 be used as a direct replacement for M20-9713845?
A: Yes. Both connectors share identical pitch (0.100"), position count (38), mounting configuration (through-hole right-angle), contact type (male pin), and current rating (3A). Electrical and mechanical compatibility is confirmed.
Q: What is the primary difference between these two connectors?
A: The M20-9713845 is obsolete, while the 890-70-038-20-002101 is active. The Preci-Dip substitute also features an extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 105°C) and glass-filled nylon insulation material.
Q: Are there any compatibility concerns with PCB layout or footprint?
A: No. Both connectors maintain identical pitch spacing, contact geometry, and through-hole mounting dimensions. Existing PCB designs require no modification.
Q: Do both connectors meet the same compliance standards?
A: Yes. Both are ROHS3 compliant and carry UL94 V-0 flammability ratings. Moisture sensitivity level is identical (MSL 1 - Unlimited).
Q: What is the packaging difference?
A: The M20-9713845 packaging is not specified in available data. The 890-70-038-20-002101 is supplied in bulk packaging.
