Substitute Part Grouping Explanation
The HT2DC20S20/F/RSP qualifies as a direct substitute based on the following critical parameters:
- Frequency Match: Both parts operate at 125kHz
- Memory Configuration: Identical 256-bit user-writable memory capacity
- Standards Compliance: Both comply with ISO 11784 and ISO 11785
- Operating Temperature: Identical range of -40°C ~ 85°C
- Physical Dimensions: Identical encapsulated form factor (11.90mm x 5.90mm)
- Technology: Both are passive RFID tags
- Environmental Compliance: Both are ROHS3 compliant and REACH unaffected
The primary distinction is product status: HT2DC20S20/F,122 is obsolete, while HT2DC20S20/F/RSP is active with significantly higher inventory availability (18,062 units vs. 936 units).

Engineering Selection Recommendations
The HT2DC20S20/F/RSP is the appropriate selection for new designs and procurement activities. This part maintains full electrical and mechanical compatibility with the obsolete HT2DC20S20/F,122 while offering the following advantages:
- Active product status ensures long-term availability and manufacturer support
- Substantially higher inventory levels (18,062 units) provide supply chain stability
- Identical compliance certifications (ROHS3, REACH unaffected) maintain regulatory requirements
- Equivalent ECCN classification (5A992C) supports export compliance continuity
Both parts are manufactured by NXP and share the same base product number (HT2DC2/HT2DC20), confirming direct functional equivalence.
Frequently Asked Questions (FAQ)
Q: Can HT2DC20S20/F/RSP be used as a direct replacement for HT2DC20S20/F,122?
A: Yes. Both parts share identical frequency (125kHz), memory configuration (256-bit user-writable), standards compliance (ISO 11784, ISO 11785), operating temperature range (-40°C ~ 85°C), and physical dimensions (11.90mm x 5.90mm). The substitute is functionally equivalent.
Q: What is the primary reason to transition from HT2DC20S20/F,122 to HT2DC20S20/F/RSP?
A: The HT2DC20S20/F,122 is classified as obsolete. The HT2DC20S20/F/RSP is an active product with significantly higher inventory availability, ensuring procurement continuity and manufacturer support.
Q: Are there any compliance differences between these parts?
A: Both parts are ROHS3 compliant and REACH unaffected. Both maintain equivalent environmental and regulatory certifications required for industrial RFID applications.
Q: Does packaging differ between these parts?
A: The HT2DC20S20/F,122 packaging is unspecified, while HT2DC20S20/F/RSP is supplied in bulk packaging. This does not affect functional compatibility.
Q: Are these parts suitable for the same operating temperature applications?
A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C, supporting equivalent thermal performance in industrial and extended-temperature environments.
