Parameter Comparison

Engineering Selection Recommendations

All three parts—Rosenberger 145799, Rosenberger 19S14H-40ML5, and Amphenol SV Microwave 1211-40001-TD—are active production components with ROHS3 compliance and MSL 1 rating, confirming suitability for modern manufacturing environments without moisture sensitivity constraints.

Selection Criteria:

Rosenberger 145799 is the primary specification. Use this part number when Rosenberger sourcing is preferred and Tape & Reel packaging is required for automated assembly lines.

Rosenberger 19S14H-40ML5 is a direct Rosenberger equivalent offering identical electrical and mechanical performance. This part is suitable when maintaining single-manufacturer sourcing is a design requirement while accepting alternative packaging or when higher inventory availability is advantageous.

Amphenol SV Microwave 1211-40001-TD is a cross-manufacturer equivalent from Amphenol SV Microwave. This part is suitable for multi-source supply chain strategies, when Cut Tape packaging aligns with manual assembly or lower-volume production workflows, or when Amphenol vendor relationships are established. The beryllium copper body and polyamide-imide dielectric provide alternative material compositions while maintaining all critical electrical parameters.

All three parts support the same frequency range (26.5 GHz), impedance (50 ohms), operating temperature range (-65°C to 155°C), and mating cycle rating (1000 cycles), confirming direct interchangeability in RF coaxial connector applications.

Frequently Asked Questions (FAQ)

Q: Can Rosenberger 19S14H-40ML5 be used as a direct replacement for Rosenberger 145799?

A: Yes. Both parts are SMP male pin plugs with 50 ohm impedance, surface mount solder termination, 26.5 GHz frequency capability, and identical operating temperature and voltage ratings. The parts are electrically and mechanically interchangeable.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, suitable for manual assembly, lower-volume production, or component kitting. Both packaging formats contain the same connector component.

Q: Can the Amphenol SV Microwave 1211-40001-TD replace the Rosenberger 145799 in my design?

A: Yes. The Amphenol part meets all critical electrical and mechanical parameters: 50 ohm impedance, SMP male pin plug configuration, surface mount solder termination, 26.5 GHz frequency support, and identical operating temperature and voltage specifications. The beryllium copper body and polyamide-imide dielectric are allowable material variations that do not affect RF performance or mechanical compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. Rosenberger 145799 and Amphenol SV Microwave 1211-40001-TD are ROHS3 compliant. Rosenberger 19S14H-40ML5 is RoHS compliant. All three parts meet environmental compliance requirements for modern electronics manufacturing.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Can these parts be used interchangeably in high-frequency RF applications?

A: Yes. All three parts support frequencies up to 26.5 GHz with 50 ohm impedance, smooth bore design, and snap-on fastening. They are suitable for telecommunications, microwave, and aerospace RF applications requiring consistent impedance and low insertion loss characteristics.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 1000 mating cycles, indicating durability for repeated connection and disconnection in field service or test environments.

Q: Are there any material differences between the substitute parts?

A: Yes. Rosenberger 145799 and 19S14H-40ML5 use brass body and center contact materials with liquid crystal polymer dielectric. Amphenol SV Microwave 1211-40001-TD uses beryllium copper body and center contact materials with polyamide-imide dielectric. Both material sets are acceptable for 50 ohm RF applications and do not affect electrical interchangeability.
