Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0901200773 are identified based on strict alignment of the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 13
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 or RoHS Compliant

Secondary Compatibility Parameters:

• Contact Finish - Mating: Gold (primary) or Tin (acceptable alternative)
• Contact Material: Brass or Copper Alloy
• Insulation Material: Polyester Glass Filled, Polybutylene Terephthalate (PBT), or Liquid Crystal Polymer (LCP)
• Operating Temperature Range: Must encompass or overlap with -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

The following parts meet these criteria and are classified as direct substitutes:

1. TE Connectivity 1-826629-3 – 13-position header, AMPMODU Mod II series, matching pitch and position count
2. Harwin M20-9991345 – 13-position header, M20 series, cuttable design, matching pitch and position count
3. Harwin M20-9991346 – 13-position header, M20 series, cuttable design, matching pitch and position count

Non-Equivalent Part:

• TE Connectivity 9-146280-0 – 40-position header; does not meet the 13-position requirement and is excluded from direct substitution

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-826629-3 is the primary substitute option. This connector maintains identical pitch, position count, and row configuration. Both the mating contact finish (gold) and post finish (tin) align with the original specification. The AMPMODU Mod II series provides equivalent electrical and mechanical performance. Operating temperature range (-65°C ~ 105°C) covers the lower portion of the original specification; applications requiring the full -55°C ~ 125°C range should verify thermal requirements. RoHS compliance is confirmed. Current rating of 5A per contact exceeds typical requirements for this connector class.

Harwin M20-9991345 and M20-9991346 are secondary substitute options. Both maintain the 13-position, single-row configuration at 0.100" pitch. The M20 series features cuttable design, enabling custom position configurations. M20-9991345 features gold mating contact finish; M20-9991346 features tin mating contact finish. Operating temperature range (-40°C ~ 105°C) is narrower than the original specification. Current rating of 3A per contact is specified. ROHS3 compliance is confirmed for both variants. Selection between these two depends on mating contact finish requirements for the application.

All substitute parts carry active product status and UL94 V-0 flammability rating, confirming ongoing availability and safety compliance.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1-826629-3 be used as a direct replacement for Molex 0901200773?

A: Yes. Both connectors share identical pitch (0.100"), position count (13), row configuration (1), mounting type (through hole), and termination method (solder). Contact finish specifications (gold mating, tin post) and material flammability ratings (UL94 V-0) are equivalent. Operating temperature range differs; verify application requirements fall within -65°C ~ 105°C.

Q: What is the difference between Harwin M20-9991345 and M20-9991346?

A: The primary difference is mating contact finish. M20-9991345 features gold mating contact finish; M20-9991346 features tin mating contact finish. Both maintain identical pitch, position count, and electrical specifications. Selection depends on connector interface requirements and corrosion resistance needs.

Q: Why is TE Connectivity 9-146280-0 not listed as a substitute?

A: TE Connectivity 9-146280-0 is a 40-position connector, whereas the Molex 0901200773 is a 13-position connector. Position count is a critical parameter for mechanical and electrical compatibility. This part does not meet substitution criteria.

Q: Are all substitute parts RoHS compliant?

A: Yes. TE Connectivity 1-826629-3 is RoHS Compliant. Harwin M20-9991345 and M20-9991346 are ROHS3 Compliant. All parts meet regulatory requirements for restricted substance elimination.

Q: What is the operating temperature limitation for substitute parts?

A: The original Molex 0901200773 operates from -55°C ~ 125°C. TE Connectivity 1-826629-3 operates from -65°C ~ 105°C. Harwin M20-9991345 and M20-9991346 operate from -40°C ~ 105°C. Applications requiring operation above 105°C or below -40°C should verify compatibility with the original part specification.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. The Molex 0901200773 and all substitute parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
