Substitute Part Grouping Explanation

Substitution eligibility for the TM3RA1-66(67) is determined by the following critical parameters:

• Base Product Number: TM3R (common platform)
• Connector Type: Jack modular connector
• Contact Configuration: 6-position 6-contact (6p6c)
• RoHS Compliance: Required
• MSL Rating: 1 (Unlimited)
• Manufacturer: Hirose Electric Co., Ltd.

The substitute part TM3RA1-66(50) shares the same base product platform (TM3R) and manufacturer, confirming compatibility within the TM3R modular connector series. Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring equivalent environmental and handling characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TM3RA1-66(50) is the manufacturer-recommended substitute for the TM3RA1-66(67). Both parts are manufactured by Hirose Electric Co., Ltd., and share the same base product platform (TM3R). The substitute maintains full RoHS compliance and MSL Level 1 rating, ensuring equivalent regulatory and environmental performance.

The primary distinction between these parts is product status: the TM3RA1-66(67) is designated Last Time Buy, while the TM3RA1-66(50) maintains Active status. This status difference, combined with higher available inventory for the substitute part (1066 Pcs versus 937 Pcs), supports the use of TM3RA1-66(50) for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can TM3RA1-66(50) be used as a direct replacement for TM3RA1-66(67)?
