Substitute Part Grouping Explanation

Substitute parts for the 526.42.1410.021 are identified based on electrical and mechanical parameter equivalence within the SMA connector plug category. The substitution logic is based on the following critical parameters that must match or exceed the main part specifications:

Electrical Parameters:

• Connector style (SMA)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Frequency capability (minimum 18 GHz)
• Voltage rating (minimum 250 V)

Mechanical Parameters:

• Mounting type (Free Hanging/In-Line)
• Contact termination method (Solder)
• Shield termination method (Crimp)
• Cable group compatibility (RG-174, RG-188, RG-316)
• Fastening type (Threaded)
• Number of ports (1)

Environmental Parameters:

• Operating temperature range (must encompass -55°C to 125°C minimum)
• Mating cycle rating (minimum 500 cycles)

Material and Finish Parameters:

• Gold plating on center contact
• Gold body finish
• Dielectric material compatibility (PTFE or equivalent)

Parts meeting all these criteria are classified as direct parametric equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the 526.42.1410.021 and the 11_SMA-50-2-5/111_NE are active production parts with equivalent electrical and mechanical specifications for SMA connector plug applications. Selection between these parts is based on the following factors:

Primary Part (526.42.1410.021):

• Manufactured by IMS Connector Systems
• Operating temperature range: -55°C to 125°C
• Center contact material: Brass with gold plating
• Body material: Brass with gold finish
• Dielectric material: PTFE
• Moisture Sensitivity Level: Not Applicable
• Current inventory: 1178 pieces

Substitute Part (11_SMA-50-2-5/111_NE):

• Manufactured by Huber+Suhner, Inc.
• Operating temperature range: -65°C to 165°C (extended range)
• Center contact material: Beryllium copper with gold plating
• Body material: Beryllium copper with gold finish
• Dielectric material: PFA and PTFE
• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)
• Current inventory: 1231 pieces

The substitute part 11_SMA-50-2-5/111_NE provides an extended operating temperature range and enhanced compliance certifications (RoHS3, REACH). Both parts share identical electrical performance at 50 ohms impedance and 18 GHz maximum frequency, with matching cable group compatibility and termination methods. Selection should be based on application temperature requirements, compliance mandates, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 11_SMA-50-2-5/111_NE be used as a direct replacement for the 526.42.1410.021?

A: Yes. Both connectors meet the same electrical specifications (50 ohms, 18 GHz), mechanical requirements (SMA plug, male pin, solder/crimp termination), and cable compatibility (RG-174, RG-188, RG-316). The substitute part operates across an extended temperature range (-65°C to 165°C versus -55°C to 125°C) and includes additional compliance certifications.

Q: What are the material differences between these two parts?

A: The primary part (526.42.1410.021) uses brass for the center contact and body with PTFE dielectric. The substitute part (11_SMA-50-2-5/111_NE) uses beryllium copper for the center contact and body with PFA and PTFE dielectric materials. Both are gold-plated and provide equivalent RF performance.

Q: Are there any temperature limitations when substituting?

A: The substitute part supports a wider temperature range (-65°C to 165°C) compared to the primary part (-55°C to 125°C). Applications operating within the primary part's temperature range will function identically with the substitute. Applications requiring extended temperature operation should use the substitute part.

Q: Do these connectors have different compliance requirements?

A: The substitute part (11_SMA-50-2-5/111_NE) is RoHS3 compliant and REACH unaffected. The primary part (526.42.1410.021) does not specify these certifications. Both parts are classified as EAR99 and share the same HTSUS code (8536.69.4010).

Q: What is the cable compatibility for these SMA connectors?

A: Both connectors are compatible with RG-174, RG-188, and RG-316 cable groups. The solder contact termination and crimp shield termination methods are identical between the two parts.

Q: Are the mating cycle ratings the same?

A: Yes. Both the 526.42.1410.021 and 11_SMA-50-2-5/111_NE are rated for 500 mating cycles, providing equivalent mechanical durability.

Q: What is the frequency performance of these connectors?

A: Both connectors support frequencies up to 18 GHz at 50 ohms impedance, making them suitable for RF and microwave applications within this bandwidth.

Q: Can I mix these connectors in the same assembly?

A: Yes. Since both connectors are SMA plugs with identical electrical and mechanical specifications, they can be used interchangeably within the same cable assembly or system design.
