Substitute Part Grouping Explanation
Substitution for the M20-9733045 is determined by the following critical parameters:
- Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical and electrical compatibility
- Number of Positions: 30 — determines connector footprint and pin count
- Number of Rows: 1 — single-row configuration
- Contact Type: Male Pin
- Mounting Type: Through Hole
- Termination: Solder
- Fastening Type: Push-Pull
- Material Flammability Rating: UL94 V-0
- RoHS Status: ROHS3 Compliant
Substitute parts meeting these criteria are functionally equivalent for applications requiring the M20-9733045 specifications. Parts with identical pitch, position count, and row configuration maintain mechanical interchangeability. Variations in contact finish thickness, insulation material composition, or operating temperature range do not affect substitution eligibility when all critical parameters align.

Engineering Selection Recommendations
Direct Equivalents (30-Position Configuration)
The parts 0022284301, 0022284304, 8-146276-0, and 890-70-030-10-002101 are direct functional equivalents to the M20-9733045. All maintain the critical 30-position, 0.100" (2.54mm) pitch single-row configuration with through-hole solder termination and push-pull fastening. All substitute parts carry active product status and meet UL94 V-0 flammability and ROHS3 compliance requirements.
Position Count Consideration
The M20-9733645 (36-position variant) differs in position count and is not a direct substitute for applications requiring exactly 30 positions. This part is listed in the original M20-9733045 substitute field but does not meet the critical position-count parameter for direct substitution.
Compliance and Availability
All six substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. Current inventory availability ranges from 701 to 914 pieces across active substitutes, ensuring supply continuity for production requirements.
Frequently Asked Questions (FAQ)
Q: Can M20-9733645 replace M20-9733045?
A: No. While both are Harwin Inc. headers with 0.100" (2.54mm) pitch and identical electrical characteristics, the M20-9733645 contains 36 positions versus 30 positions in the M20-9733045. Position count is a critical substitution parameter. Use M20-9733645 only for applications specifically designed for 36-position connectors.
Q: Are Molex 0022284301 and 0022284304 interchangeable?
A: Both Molex parts maintain identical 30-position, 0.100" (2.54mm) pitch configuration and are mechanically and electrically compatible. The primary difference is contact finish: 0022284301 features tin mating finish, while 0022284304 features gold mating finish. Selection depends on application contact resistance requirements.
Q: What is the difference between TE Connectivity 8-146276-0 and the original M20-9733045?
A: Both maintain 30-position, 0.100" (2.54mm) pitch configuration with gold mating finish and 3A current rating. The 8-146276-0 uses Liquid Crystal Polymer (LCP) insulation material versus Polyamide (PA6T) in the original, and operates across a wider temperature range (-65°C to 105°C versus -40°C to 105°C). These differences do not affect mechanical or electrical substitution compatibility.
Q: Does Preci-Dip 890-70-030-10-002101 meet the same specifications?
A: Yes. The 890-70-030-10-002101 maintains 30-position, 0.100" (2.54mm) pitch configuration with gold mating finish, 3A current rating, and UL94 V-0 flammability rating. It operates across an extended temperature range (-55°C to 125°C) and includes 150VDC voltage rating specification. All critical substitution parameters align with the M20-9733045.
Q: Are all substitutes ROHS3 compliant?
A: Five of the six substitutes carry ROHS3 compliance certification. The TE Connectivity 8-146276-0 carries RoHS Compliant status without specific ROHS3 designation. Both certifications meet regulatory requirements for lead-free component usage.
Q: Can these connectors be used in automotive applications?
A: The Molex parts (0022284301 and 0022284304) explicitly list automotive applications. The TE Connectivity 8-146276-0 and Preci-Dip 890-70-030-10-002101 do not specify automotive applications in provided data. Harwin M20-9733045 and M20-9733645 do not list specific applications. Verify application requirements against manufacturer specifications before selection.
