Parameter Comparison

Engineering Selection Recommendations

The R41-A624B serves as the direct substitute for the R41-A901B. Both components share identical electrical specifications, mechanical interfaces, and thermal operating ranges. The primary distinction is product lifecycle status: R41-A901B is Obsolete while R41-A624B maintains Active status with Mitsumi Electric Company Ltd, ensuring continued manufacturing support, quality assurance, and supply chain availability.

For new designs or system refreshes, R41-A624B is the appropriate selection. For legacy system maintenance requiring exact form-fit-function compatibility, R41-A624B provides equivalent performance across all specified parameters including impedance, frequency response, insertion loss, and environmental ratings.

Both components carry identical compliance designations (ECCN: EAR99; HTSUS: 8536.69.4010) and moisture sensitivity level (MSL: 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can R41-A624B directly replace R41-A901B in existing assemblies?

A: Yes. Both connectors share identical electrical parameters (100 Ohms impedance, 2 GHz maximum frequency, 0.10 dB insertion loss), mechanical mounting configuration (through-hole solder termination), and environmental specifications (-40°C ~ 105°C operating range, 100 V voltage rating). Physical form factor and pin configuration are equivalent.

Q: What is the primary reason for substitution?
