Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the MS-156C are determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Impedance: 50 Ohms (mandatory)
• Connector Style: Coaxial Switch - 4mm Plug Dia (mandatory)
• Connector Type: Receptacle, Female Socket (mandatory)
• Contact Termination: Solder (mandatory)
• Mounting Type: Surface Mount (mandatory)
• Operating Temperature Range: -40°C ~ 85°C (mandatory)
• Mating Cycles: 100 (mandatory)

Secondary Considerations:

• Frequency - Max: Parts rated at 11 GHz or higher are direct equivalents; parts rated at 6 GHz are functional substitutes with reduced frequency capability
• Insertion Loss: Variations indicate different contact materials (Copper Alloy vs. Beryllium Copper) but do not affect substitutability
• Packaging Format: Tape & Reel (TR) and Strip packaging are interchangeable for component selection; packaging choice depends on assembly process requirements
• RoHS Status: All parts maintain RoHS compliance; ROHS3 designation indicates updated compliance documentation

The MS-156C is grouped with MS-156C(20), MS-156C3, and MS-156C3(20) as parametric equivalents sharing identical electrical specifications. The MS-156HF series (MS-156HF, MS-156HF(01), MS-156HF(20), MS-156HF(22)) represents manufacturer-recommended substitutes with equivalent mechanical and thermal characteristics but reduced maximum frequency rating (6 GHz vs. 11 GHz).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitution): MS-156C(20), MS-156C3, and MS-156C3(20) are direct parametric equivalents to MS-156C. All maintain identical electrical specifications including 11 GHz maximum frequency and 0.4 dB insertion loss. Selection among these parts depends on packaging preference (all available in Tape & Reel format) and inventory availability. MS-156C3 and MS-156C3(20) carry ROHS3 compliance designation, providing updated regulatory documentation for applications requiring current RoHS certification standards.

Manufacturer-Recommended Substitutes (Functional Substitution): The MS-156HF series (MS-156HF, MS-156HF(01), MS-156HF(20), MS-156HF(22)) represents manufacturer-approved alternatives. These parts meet all mechanical, thermal, and impedance requirements but operate at a reduced maximum frequency of 6 GHz compared to the MS-156C's 11 GHz rating. The MS-156HF series uses Beryllium Copper center contacts, resulting in lower insertion loss (0.15 dB vs. 0.4 dB). Selection of MS-156HF variants is appropriate for applications operating below 6 GHz where the improved insertion loss performance provides system benefits. Packaging options include Tape & Reel (MS-156HF, MS-156HF(20), MS-156HF(22)) and Strip (MS-156HF(01)) formats.

Compliance Considerations: All listed parts maintain RoHS compliance. Applications requiring ROHS3 documentation should specify MS-156C3 or MS-156C3(20). All parts are MSL 1 (unlimited moisture sensitivity), eliminating bake-out requirements for standard manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can MS-156HF parts replace MS-156C in all applications? A: MS-156HF parts are functional substitutes for applications operating at frequencies up to 6 GHz. Applications requiring operation above 6 GHz must use MS-156C, MS-156C(20), MS-156C3, or MS-156C3(20). All other electrical and mechanical parameters are equivalent.

Q: What is the difference between MS-156C and MS-156C3? A: MS-156C and MS-156C3 are parametrically identical. The primary difference is RoHS compliance documentation: MS-156C carries RoHS Compliant status, while MS-156C3 carries ROHS3 Compliant status. Both meet current RoHS requirements; selection depends on documentation requirements for your application.

Q: Does packaging format affect component performance? A: No. Packaging format (Tape & Reel vs. Strip) does not affect electrical or mechanical performance. Selection depends on assembly process requirements. Tape & Reel packaging is standard for automated pick-and-place assembly; Strip packaging is used for manual or alternative assembly processes.

Q: Why does MS-156HF have lower insertion loss than MS-156C? A: Insertion loss differences result from center contact material composition. MS-156HF uses Beryllium Copper (0.15 dB insertion loss), while MS-156C uses Copper Alloy (0.4 dB insertion loss). Both materials meet the 50 Ohm impedance and mechanical requirements; material selection reflects design optimization for different frequency ranges.

Q: Are all parts in this list interchangeable for PCB layout? A: Yes. All parts share identical mechanical dimensions, mounting footprint, and solder termination specifications. PCB layout and assembly processes require no modification when substituting between listed parts.

Q: What does MSL 1 mean for manufacturing? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. These parts do not require bake-out procedures before soldering and can be stored in standard manufacturing environments without desiccant packaging.
