Rosenberger 157634 SMA Right Angle Jack PCB Equivalent & Substitute Parts

Part Overview

The Rosenberger 157634 is an SMA connector jack designed for surface mount PCB applications with board edge, cutout mounting. This female socket connector operates at 50 ohms impedance and supports frequencies up to 18 GHz. The connector features solder termination for both center contact and shield, with gold plating on brass body and beryllium copper center contact. The part is active in production and RoHS3 compliant, making it suitable for modern RF and microwave applications requiring reliable coaxial connectivity.

Equivalent substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Rosenberger 157634 is permissible with parts that maintain identical electrical and mechanical specifications across all critical parameters. The substitution logic is based on the following key parameters that must remain constant:

Electrical Parameters:

• Connector style: SMA
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 18 GHz
• Number of ports: 1

Mechanical Parameters:

• Mounting type: Board Edge, Cutout; Surface Mount
• Contact termination: Solder
• Shield termination: Solder
• Fastening type: Threaded
• Center contact material: Beryllium Copper
• Body material: Brass
• Dielectric material: PTFE

Environmental & Compliance Parameters:

• Packaging: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts (Molex 0732511143, Cinch Connectivity Solutions 142-0721-882, and Würth Elektronik 60312202114307) satisfy these core requirements and are therefore electrically and mechanically interchangeable with the Rosenberger 157634.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status and full RoHS3 compliance, ensuring regulatory alignment with modern electronics standards. The Molex 0732511143 and Würth Elektronik 60312202114307 both specify ROHS3 compliance, matching the primary part exactly. The Cinch Connectivity Solutions 142-0721-882 carries RoHS compliance certification.

Molex 0732511143 operates at 500 V voltage rating, exceeding the primary part specification of 480 V. Operating temperature range is not specified for this part.

Cinch Connectivity Solutions 142-0721-882 operates at 335 V voltage rating and supports 500 mating cycles, compared to the primary part's 100 mating cycles. This part maintains the full operating temperature range of -65°C to 165°C.

Würth Elektronik 60312202114307 operates at 335 V voltage rating and supports 500 mating cycles. This part maintains the full operating temperature range of -65°C to 165°C and carries REACH Affected status notification.

All substitute parts maintain identical electrical performance at 50 ohms impedance and 18 GHz maximum frequency. Selection among substitutes should be based on application voltage requirements, expected mating cycle count, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0732511143 be used as a direct replacement for the Rosenberger 157634?

A: Yes. Both parts share identical electrical specifications (50 ohms, 18 GHz maximum frequency), mechanical configuration (SMA jack, female socket, board edge cutout mounting, solder termination), and packaging (Tape & Reel). The Molex part provides higher voltage rating (500 V versus 480 V). Operating temperature range is not specified for the Molex part; verify application requirements if operating near temperature extremes.

Q: What are the differences in voltage rating among the substitute parts?

A: The Rosenberger 157634 is rated at 480 V. The Molex 0732511143 is rated at 500 V. Both the Cinch Connectivity Solutions 142-0721-882 and Würth Elektronik 60312202114307 are rated at 335 V. Applications requiring operation above 335 V should use either the Rosenberger or Molex parts.

Q: How do mating cycle ratings differ?

A: The Rosenberger 157634 is rated for 100 mating cycles. Both the Cinch Connectivity Solutions 142-0721-882 and Würth Elektronik 60312202114307 are rated for 500 mating cycles, providing greater durability for high-cycle applications. The Molex 0732511143 does not specify mating cycle rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Rosenberger 157634, Molex 0732511143, and Würth Elektronik 60312202114307 are ROHS3 compliant. The Cinch Connectivity Solutions 142-0721-882 is RoHS compliant. All parts meet current regulatory requirements for lead-free electronics.

Q: Do all parts support the same operating temperature range?

A: The Rosenberger 157634, Cinch Connectivity Solutions 142-0721-882, and Würth Elektronik 60312202114307 all operate from -65°C to 165°C. The Molex 0732511143 does not specify operating temperature range; confirm suitability for your application environment.

Q: Are these parts available in the same packaging format?

A: Yes. All four parts (Rosenberger 157634, Molex 0732511143, Cinch Connectivity Solutions 142-0721-882, and Würth Elektronik 60312202114307) are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
