Engineering Selection Recommendations
TE Connectivity 5227433-1 (Primary Part) The original part is RoHS Compliant and REACH Unaffected. This part is suitable for applications where standard RoHS compliance and unrestricted REACH status are required. Bulk packaging is appropriate for high-volume production environments.
TE Connectivity 5227661-1 This substitute maintains all core electrical and mechanical specifications with identical tin plating on the center contact. The part is ROHS3 Compliant and REACH Affected. Tube packaging is suitable for lower-volume applications or kitted assemblies. This part is functionally equivalent for all 50-ohm BNC jack applications within the specified operating temperature range.
TE Connectivity 5227676-1 This substitute features gold plating on the center contact, providing enhanced corrosion resistance compared to the tin-plated primary part. RoHS Compliant and REACH Unaffected status matches the original part. Bulk packaging supports production environments. Gold plating extends contact durability in applications subject to environmental exposure or frequent mating cycles.
TE Connectivity 5227677-1 This substitute combines gold center contact plating with ROHS3 Compliant and REACH Affected regulatory status. Bulk packaging is provided. The gold plating offers the same corrosion resistance benefits as part 5227676-1 with updated RoHS3 compliance.
Amphenol RF 031-6121 This cross-manufacturer substitute maintains all core BNC jack specifications with the following distinctions: beryllium copper center contact material, PTFE dielectric material, and extended operating temperature range (-65°C ~ 165°C). ROHS3 Compliant and REACH Affected status applies. The part includes three components (connector, lockwasher, nut) and specifies 0.2dB insertion loss. This part is suitable for applications requiring extended temperature performance or PTFE dielectric properties.
Frequently Asked Questions (FAQ)
Q: Can I substitute the TE Connectivity 5227433-1 with any of the listed parts?
A: All listed parts maintain the core electrical and mechanical specifications required for BNC jack 50-ohm panel mount applications. Substitution is valid based on impedance, connector type, mounting configuration, and termination method. Differences in center contact plating, dielectric material, and operating temperature range do not affect substitution eligibility for standard applications within the specified operating parameters.
Q: What is the difference between tin and gold plating on the center contact?
A: The primary part 5227433-1 features tin plating. Substitute parts 5227676-1, 5227677-1, and 031-6121 feature gold plating. Gold plating provides enhanced corrosion resistance and is suitable for applications with extended environmental exposure or frequent mating cycles. Tin plating is adequate for standard indoor applications with controlled environmental conditions.
Q: Does packaging format affect electrical performance?
A: No. Packaging format (Bulk vs. Tube) is a logistics and handling consideration only. Part 5227661-1 is supplied in Tube packaging while other TE Connectivity substitutes are supplied in Bulk packaging. Electrical and mechanical performance is identical regardless of packaging format.
Q: What is the significance of ROHS3 vs. RoHS Compliant status?
A: Both designations indicate RoHS compliance. ROHS3 represents the current RoHS 3 directive compliance standard. Parts marked RoHS Compliant meet RoHS requirements. Selection between these designations depends on customer or regulatory requirements for the specific application or market region.
Q: How does the Amphenol RF 031-6121 differ from TE Connectivity substitutes?
A: The Amphenol RF 031-6121 is a cross-manufacturer substitute with the following differences: beryllium copper center contact material (vs. phosphor bronze), PTFE dielectric material (vs. PMP), extended operating temperature range (-65°C ~ 165°C vs. -55°C ~ 85°C), and specified insertion loss of 0.2dB. The part includes mounting hardware (lockwasher and nut). These differences make it suitable for applications requiring extended temperature performance or specific dielectric properties.
Q: Are all substitute parts rated for the same frequency range?
A: Yes. All substitute parts are rated for maximum frequency of 4 GHz, matching the primary part specification. Frequency performance is equivalent across all listed substitutes.
Q: What is the REACH status and why does it matter?
A: REACH Affected status indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected status indicates no REACH-regulated substances are present. Selection depends on customer requirements and end-use market regulations. The primary part 5227433-1 is REACH Unaffected, while some substitutes are REACH Affected.
Q: Can I use the 031-6121 in applications with operating temperatures below -55°C?
A: Yes. The Amphenol RF 031-6121 is rated for -65°C ~ 165°C operating temperature, which extends below the -55°C ~ 85°C range of the primary part and TE Connectivity substitutes. This part is suitable for cryogenic or extreme cold environment applications.
