Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict alignment of electrical and mechanical parameters. The following criteria establish substitutability for the 147102-3:

Primary Substitution Criteria:

• Connector type: Receptacle, Bottom or Top Entry
• Number of positions: 6
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Surface Mount
• Contact type: Female Socket
• Fastening type: Push-Pull
• Contact finish - mating: Gold
• Termination: Solder

Compatibility Considerations: Substitute parts must maintain mechanical compatibility with existing mating connectors and PCB layouts. Electrical parameters including current rating and operating temperature must meet or exceed application requirements. Contact finish specifications and insulation materials must be compatible with the intended application environment.

The Harwin Inc. M20-7870342 satisfies all primary substitution criteria and maintains mechanical and electrical compatibility with the 147102-3.

Parameter Comparison

Engineering Selection Recommendations

The Harwin M20-7870342 is an active product with full availability and current manufacturing support, making it the primary substitute for the obsolete TE Connectivity 147102-3. Both connectors are ROHS3 compliant and share identical mechanical and mating specifications.

Electrical Compatibility: The M20-7870342 provides a higher current rating of 3A compared to the 147102-3 at 2A, ensuring adequate performance in applications designed for the original part. The M20-7870342 operates within the temperature range of -40°C ~ 105°C, which covers standard industrial and commercial applications. Applications requiring the full -65°C ~ 125°C range of the 147102-3 must evaluate the reduced temperature specification of the substitute.

Compliance Status: Both parts maintain ROHS3 compliance and share identical ECCN and HTSUS classifications, supporting regulatory and trade compliance requirements.

Supply Chain: The M20-7870342 is currently in active production with substantial inventory availability, eliminating supply chain risk associated with the obsolete 147102-3.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M20-7870342 directly replace the TE Connectivity 147102-3 in existing designs?

A: Yes. Both connectors share identical mechanical specifications including pitch, number of positions, row configuration, and mounting type. The M20-7870342 maintains full mechanical and electrical compatibility with existing mating connectors and PCB layouts designed for the 147102-3.

Q: What are the key differences between these two connectors?

A: The primary differences are product status, current rating, and operating temperature range. The M20-7870342 is an active product with 3A current rating and -40°C ~ 105°C operating range, compared to the obsolete 147102-3 with 2A rating and -65°C ~ 125°C range. Both maintain identical mating contact specifications and gold plating.

Q: Are there temperature limitations when substituting the M20-7870342 for the 147102-3?

A: The M20-7870342 operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must evaluate alternative solutions, as the substitute does not cover the full temperature range of the original part.

Q: Do both connectors use the same packaging?

A: The 147102-3 packaging is not specified in available documentation. The M20-7870342 is supplied in tube packaging. Packaging differences do not affect connector compatibility but may impact handling and assembly procedures.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TE Connectivity 147102-3 and Harwin M20-7870342 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the current rating difference and does it affect compatibility?

A: The M20-7870342 provides 3A current rating compared to 2A for the 147102-3. This higher rating ensures the substitute meets or exceeds the electrical requirements of applications designed for the original part.
