Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HRM-100-1(40) is determined by strict equivalence across the following critical parameters:

• Connector style and type (SMA, Plug, Male Pin)
• Impedance specification (50 Ohms)
• Cable compatibility (RG-405 semi-rigid)
• Termination method (Solder for both contact and shield)
• Mounting configuration (Free Hanging In-Line)
• Frequency rating (12.4 GHz maximum)
• Operating temperature range (-55°C ~ 125°C)
• Mating cycle rating (1000 cycles)
• Dielectric material (PTFE)
• RoHS compliance status

The HRM-100-1S(40) meets all these criteria and is classified as a parametric equivalent. Variations in body material composition and finish do not affect electrical performance or mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The HRM-100-1S(40) is a direct parametric equivalent to the HRM-100-1(40) across all specified electrical and mechanical parameters. Both parts maintain identical impedance, frequency response, temperature operating range, and termination specifications. The HRM-100-1S(40) carries Active product status, ensuring continued availability and supply chain support, whereas the HRM-100-1(40) is designated Last Time Buy. For new designs or ongoing production requiring this connector specification, the HRM-100-1S(40) is the appropriate selection. Both parts maintain RoHS compliance and equivalent certification status.

Frequently Asked Questions (FAQ)

Q: Can HRM-100-1S(40) be used as a direct replacement for HRM-100-1(40)?

A: Yes. Both parts are parametrically equivalent across all critical specifications including connector style, impedance, frequency rating, termination method, and operating temperature range. Electrical and mechanical compatibility is maintained.

Q: What is the difference between these two parts?

A: The primary differences are body material composition (Brass with Nickel finish versus Stainless Steel) and product status (Last Time Buy versus Active). These differences do not affect electrical performance or mechanical interface compatibility.

Q: Why is HRM-100-1(40) listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory may be available for a limited period. The HRM-100-1S(40) provides equivalent functionality with ongoing production support.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts interface with RG-405 semi-rigid cable, utilize identical solder termination methods, and maintain the same mechanical mounting configuration.

Q: What certifications apply to both parts?

A: Both parts are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.
