Substitute Part Grouping Explanation

Substitution relationships for the MS-156HF are determined by strict equivalence in the following critical parameters: connector style (Coaxial Switch - 4mm Plug Dia), connector type (Receptacle, Female Socket), impedance (50 Ohms), mounting type (Surface Mount), contact and shield termination (Solder), operating temperature range (-40°C ~ 85°C), mating cycles (100), and RoHS compliance status.

Substitute parts are grouped into the following categories:

Direct Equivalents (Packaging Variant): MS-156HF(01) differs only in packaging format (Strip vs. Tape & Reel), maintaining identical electrical and mechanical specifications.

Manufacturer Recommended Substitutes: MS-156C and MS-156C(20) are approved alternatives within the MS-156 base product family. These parts maintain core connector geometry, termination method, and mounting characteristics. The MS-156C series operates at a higher maximum frequency (11 GHz vs. 6 GHz) and exhibits different insertion loss (0.4 dB vs. 0.15 dB) due to center contact material variation (Copper Alloy vs. Beryllium Copper).

Packaging and Feature Variants: MS-156HF(20) and MS-156HF(22) maintain identical electrical performance to MS-156HF. MS-156HF(22) includes an additional Pick and Place Cap feature for automated assembly applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and RoHS compliance, ensuring regulatory alignment with the original MS-156HF specification.

For applications operating at frequencies up to 6 GHz with insertion loss sensitivity: MS-156HF, MS-156HF(01), MS-156HF(20), and MS-156HF(22) are functionally equivalent. Selection among these variants depends on packaging requirements (Tape & Reel vs. Strip) and assembly process compatibility (standard vs. Pick and Place Cap).

For applications requiring higher frequency capability (up to 11 GHz): MS-156C and MS-156C(20) provide extended frequency range. The trade-off is increased insertion loss (0.4 dB vs. 0.15 dB) due to center contact material composition. These parts are suitable for designs where frequency headroom is prioritized over signal loss minimization.

For supply chain optimization: All parts share identical base product number (MS-156) and core mechanical interface, supporting design flexibility without PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can MS-156C be used as a direct replacement for MS-156HF in existing designs?

A: MS-156C maintains mechanical and electrical compatibility at the connector interface level. However, the increased insertion loss (0.4 dB vs. 0.15 dB) and extended frequency capability (11 GHz vs. 6 GHz) must be evaluated against circuit performance requirements. If the design operates below 6 GHz and insertion loss is a critical parameter, MS-156HF variants are preferred.

Q: What is the difference between MS-156HF and MS-156HF(22)?

A: Both parts are electrically and mechanically identical. MS-156HF(22) includes a Pick and Place Cap feature, which is a mechanical addition for automated assembly processes. Selection depends on manufacturing equipment compatibility.

Q: Are MS-156HF(01) and MS-156HF interchangeable?

A: Yes. Both parts have identical electrical and mechanical specifications. The only difference is packaging format: MS-156HF(01) is supplied in Strip packaging, while MS-156HF is supplied in Tape & Reel. Selection depends on assembly line requirements and inventory management practices.

Q: What does the suffix (20) or (01) or (22) indicate?

A: These suffixes denote packaging variants or assembly-specific configurations within the same electrical specification family. They do not indicate performance differences.

Q: Can I substitute MS-156C(20) for MS-156HF in a 50 Ohm RF circuit?

A: Yes, from an impedance and connector geometry perspective. However, the higher insertion loss of MS-156C(20) (0.4 dB vs. 0.15 dB) will impact signal attenuation. Verify that circuit gain budgets accommodate this difference.

Q: Are all listed parts RoHS compliant?

A: Yes. All substitute parts listed carry RoHS Compliant status and MSL Rating 1 (Unlimited), meeting environmental and moisture sensitivity requirements.
