Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 916A524FT is determined by strict equivalence across critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters: Connector style (SMA), connector type (Plug, Male Pin), impedance (50 Ohms), and dielectric material (PTFE) must remain constant. Frequency maximum must equal or exceed 12.5 GHz to maintain signal integrity across the operating bandwidth.

Mechanical Parameters: Contact termination (Solder Tab), shield termination (Solder), mounting type (Panel Mount), mounting feature (Flange), and fastening type (Threaded) must be identical. Number of ports must equal 1.

Material and Environmental Parameters: Center contact material (Brass), center contact plating (Gold), and dielectric material (PTFE) establish material compatibility. Operating temperature range must encompass or exceed -65°C to 165°C. RoHS compliance status must match.

Reliability Parameters: Mating cycles and moisture sensitivity level provide durability benchmarks. Substitute parts must maintain MSL 1 (Unlimited) classification.

The Hirose Electric HRM-406S(40) qualifies as a substitute based on alignment with these core parameters.

Engineering Selection Recommendations

Primary Part: 916A524FT

The Winchester Interconnect 916A524FT remains the specified component for applications requiring the full operating temperature range of -65°C to 165°C. This part is active in production status with RoHS compliance certification and unlimited moisture sensitivity level rating. Current inventory of 1,082 pieces supports immediate procurement requirements.

Substitute Part: HRM-406S(40)

The Hirose Electric HRM-406S(40) serves as a qualified substitute when the primary part is unavailable. This component maintains electrical equivalence across all critical RF parameters including 50 ohm impedance, SMA connector style, and PTFE dielectric material. The substitute demonstrates enhanced reliability with 1,000 mating cycles compared to 500 cycles for the primary part.

Operating Temperature Consideration:

The HRM-406S(40) operates within -55°C to 125°C range, which is narrower than the primary part's -65°C to 165°C specification. Applications requiring operation below -55°C or above 125°C must use the 916A524FT. Applications operating within the -55°C to 125°C window may use either part without thermal performance degradation.

Compliance and Certification:

Both parts maintain RoHS compliance status and MSL 1 (Unlimited) moisture sensitivity level classification, ensuring equivalent environmental and regulatory compliance for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the HRM-406S(40) be used as a direct replacement for the 916A524FT in all applications?

A: The HRM-406S(40) is electrically and mechanically equivalent for applications operating within -55°C to 125°C. Applications requiring operation outside this temperature range must use the 916A524FT.

Q: What are the key electrical parameters that must match for substitution?

A: Connector style (SMA), connector type (Plug, Male Pin), impedance (50 Ohms), dielectric material (PTFE), and frequency capability must be identical. Both parts meet these requirements.

Q: Does the substitute part have different solder termination specifications?

A: Both parts use solder termination for contact and shield. The 916A524FT specifies solder tab contact termination, while the HRM-406S(40) specifies solder contact termination. Both methods provide equivalent electrical connection in panel mount applications.

Q: What is the significance of the mating cycle difference?

A: The HRM-406S(40) supports 1,000 mating cycles compared to 500 cycles for the 916A524FT. This indicates enhanced mechanical durability for the substitute part. Applications with frequent connector mating may benefit from the substitute's extended cycle rating.

Q: Are both parts RoHS compliant?

A: Yes, both the 916A524FT and HRM-406S(40) are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level classification.

Q: What packaging formats are available?

A: The 916A524FT is available in standard packaging format. The HRM-406S(40) is supplied in bulk packaging. Verify packaging requirements with procurement specifications before ordering.

Q: How do the body materials differ between these parts?

A: The 916A524FT uses brass body material with nickel finish. The HRM-406S(40) uses stainless steel body material. Both materials provide equivalent RF performance and environmental protection in standard applications.
