Rosenberger 136644 SMP Straight Plug PCB Coaxial Connector Equivalent & Substitute Parts

Part Overview

The Rosenberger 136644 is an SMP connector plug designed for surface mount PCB applications in 50 Ohm RF systems. This male pin coaxial connector operates across frequencies up to 40 GHz and is rated for operating temperatures between -65°C and 155°C. The connector features solder termination for both center contact and shield, with a snap-on fastening mechanism and limited detent design. The part is currently active in production and ROHS3 compliant. Equivalent substitute parts are necessary when primary inventory is unavailable, when alternative packaging formats are required, or when design specifications allow for compatible connector variants from different manufacturers that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Rosenberger 136644 are qualified based on strict equivalence across the following critical parameters: connector style (SMP), connector type (Plug, Male Pin), impedance (50 Ohms), mounting type (Surface Mount), contact and shield termination method (Solder), fastening type (Snap-On), maximum frequency (40 GHz), number of ports (1), voltage rating (335 V), and mating cycle rating (500). All substitute parts must maintain ROHS3 compliance and operate within the specified temperature range. The three qualified substitute parts are manufactured by Molex and represent different series variants and packaging configurations while maintaining full electrical and mechanical compatibility with the primary Rosenberger connector.

Parameter Comparison

Engineering Selection Recommendations

All three Molex substitute parts are active production components with ROHS3 compliance, matching the status and regulatory requirements of the primary Rosenberger 136644 connector. Selection between substitutes depends on specific application requirements and packaging constraints.

Molex 0734153310 (Series 73415) is a direct functional equivalent available in Tape & Reel packaging with unlimited moisture sensitivity rating. This part maintains identical electrical specifications and operating temperature range to the Rosenberger connector.

Molex 0734156183 (Series 73415) offers an extended operating temperature range of -65°C to 165°C, providing 10°C additional high-temperature capability compared to the primary part. This variant includes specified insertion loss of 0.1 dB and features Liquid Crystal Polymer dielectric material. Moisture sensitivity is not applicable for this variant. REACH compliance status differs from the primary part.

Molex 0853050232 (Series 85305) provides equivalent electrical performance with alternative packaging in Cut Tape and Digi-Reel format. This part incorporates Liquid Crystal Polymer dielectric material and maintains the standard operating temperature range of -65°C to 155°C.

Selection should be based on packaging requirements, temperature operating envelope, and supply chain availability. All three parts satisfy the core electrical and mechanical requirements for direct substitution in 50 Ohm SMP surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0734153310 be used as a direct replacement for Rosenberger 136644?

A: Yes. Both parts share identical electrical specifications including 50 Ohm impedance, 40 GHz maximum frequency, 335 V voltage rating, and 500 mating cycles. Both feature solder termination, snap-on fastening, and operate across -65°C to 155°C. Packaging format is identical (Tape & Reel).

Q: What is the difference between Molex 0734156183 and the other substitutes?

A: Molex 0734156183 extends the maximum operating temperature to 165°C (10°C higher than the primary part) and specifies insertion loss at 0.1 dB. It uses Liquid Crystal Polymer dielectric material and has not applicable moisture sensitivity rating. REACH compliance status differs from the primary Rosenberger connector.

Q: Why is Molex 0853050232 packaged differently?

A: Molex 0853050232 is supplied in Cut Tape and Digi-Reel packaging rather than standard Tape & Reel format. This alternative packaging may be selected based on production line requirements or inventory management preferences. Electrical and mechanical specifications remain equivalent to the primary part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three Molex substitute parts are ROHS3 compliant, matching the regulatory status of the Rosenberger 136644.

Q: Can these connectors be used interchangeably in production?

A: Yes, provided that packaging format and operating temperature requirements are compatible with the specific application. All parts maintain identical electrical performance at 50 Ohms impedance and 40 GHz maximum frequency. Verify that the selected substitute's operating temperature range encompasses the application's thermal requirements.

Q: What is the moisture sensitivity difference between the substitutes?

A: Rosenberger 136644 and Molex 0734153310 and 0853050232 all have MSL 1 (Unlimited) rating. Molex 0734156183 has not applicable moisture sensitivity, indicating different handling requirements during storage and assembly.

Q: Are there differences in center contact material between parts?

A: Rosenberger 136644 specifies Beryllium Copper center contact material. All three Molex substitutes use Brass center contact material. Both materials are plated with gold and maintain equivalent electrical performance at the specified impedance and frequency range.
